Answer:
Natural selection results in evolution.
Explanation:
Natural selection is the separation of types of individuals in different environments, like geographical isolation. Due to this, the offspring will soon evolve and create a new species, known as evolution.
Answer:
B) a sequence of three nucleotides
Explanation:
A codon is the sequence of three nucleotides that decide that which particular amino acid would be incorporated in the polypeptide chain. Each codon code for a particular amino acid and responsible for the primary structure of proteins.
During translation the transfer RNA have the anticodon on its one side and amino acid bound to it on its other side. It adds the amino acids to growing polypeptide chain by binding to particular codon on messenger RNA.
Example; AUG is the starting codon for every protein and code for methionine in eukaryotes and anticodon for it is UAC.
Answer: It is a technique used to amplify a segment of DNA of interest or produce lots and lots of copies. In other words, PCR enables you to produce millions of copies of a specific DNA sequence from an initially small sample – sometimes even a single copy. (looked it up on google lol)
